Perkin Elmer Turbo-Mass Gas Chromatography System. Gas Chromatography (Gc), Is A Common Type Of Chromatography Used In Analytical Chemistry For Separating And Analyzing Compounds That Can Be Vaporized Without Decomposition. Typical Uses Of Gc Include Testing The Purity Of A Particular Substance, Or Separating The Different Components Of A Mixture (The Relative Amounts Of Such Components Can Also Be Determined). In Some Situations, Gc May Help In Identifying A Compound. In Preparative Chromatography, Gc Can Be Used To Prepare Pure Compounds From A Mixture. In Gas Chromatography, The Mobile Phase (Or Moving Phase) Is A Carrier Gas, Usually An Inert Gas Such As Helium Or An Unreactive Gas Such As Nitrogen. The Stationary Phase Is A Microscopic Layer Of Liquid Or Polymer On An Inert Solid Support, Inside A Piece Of Glass Or Metal Tubing Called A Column (A Homage To The Fractionating Column Used In Distillation). The Instrument Used To Perform Gas Chromatography Is Called A Gas Chromatograph (Or Aerograph, Gas Separator). The Gaseous Compounds Being Analyzed Interact With The Walls Of The Column, Which Is Coated With A Stationary Phase. This Causes Each Compound To Elute At A Different Time, Known As The Retention Time Of The Compound. The Comparison Of Retention Times Is What Gives Gc Its Analytical Usefulness.
